title: 3-[1-(2-Hy-droxy-anilino)ethyl-idene]-3H-chromen-2,4-dione.
abstract: The title compound is a new amino-coumarin derivative, C17H13NO4, and was synthesized by the condensation of 2-amino-phenol and 3-acetyl-4-hy-droxy-coumarin. An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, the molecules are linked into chains extending in the [010] direction by O-H⋯O hydrogen bonds. There is also a π-π stacking inter-action between the bicyclic coumarin fragment and the phenol ring [centroid-centroid distance = 3.7510 (14) Å], and these ring systems form between them a dihedral angle of 53.3 (2)°. Intermolecular hydrogen bond C-H⋯O hydrogen bonding is also observed in the interconnection of the crystal packing.
